LXC容器不能启动

我的CentOS LXC容器不能在Ubuntu 14.10机器上启动。 我认为问题是在重新启动后才开始的，但我不确定。

在yum更新之后，我遇到了一个类似的问题，那就是init脚本被不是LXC的股票所取代。 他们试图启动udev等等，但是这次我对所有的CentOS实例都有这个问题，即使是新创build的。

主机操作系统：Ubuntu14.10 64bit
客户操作系统：Centos 6.5 64bit

root@ubuntu-mvutcovici:~# lxc-start --logfile stash-lxc.log --logpriority DEBUG -dn stash lxc-start: lxc_start.c: main: 337 The container failed to start. lxc-start: lxc_start.c: main: 339 To get more details, run the container in foreground mode. lxc-start: lxc_start.c: main: 341 Additional information can be obtained by setting the --logfile and --logpriority options. root@ubuntu-mvutcovici:~# 

这里是stash-lxc.log文件的内容：

• 在btrfs上处理LXC容器的正确方法
• 计算两台主机上安装的软件包之间的差异列表
• 使用静态IP设置桥接LXC容器
• Microsoft Windows相当于LXC
• Red Hat / CentOS EL6上的Linux容器（LXC） – lxc-create与libvirt？

要创build我已经使用的所有CentOS实例：

 root@ubuntu-mvutcovici:~# lxc-create -t centos -f lxc-mircea.conf -n stash root@ubuntu-mvutcovici:~# cat lxc-mircea.conf lxc.network.type = veth lxc.network.link = br0 lxc.network.flags = up 

编辑 ：似乎将lxc.aa_allow_incomplete = 1添加到/ var / lib / lxc /存储/configuration文件是解决启动问题。 CentOS LXC应该如何让应用程序装甲再次共存？

从lxc.container.conf手册页：

  lxc.aa_allow_incomplete Apparmor profiles are pathname based. Therefore many file restrictions require mount restrictions to be effective against a determined attacker. However, these mount restrictions are not yet implemented in the upstream kernel. Without the mount restrictions, the apparmor profiles still protect against accidental damager. If this flag is 0 (default), then the container will not be started if the kernel lacks the apparmor mount features, so that a regression after a kernel upgrade will be detected. To start the container under partial apparmor protection, set this flag to 1. 

EDIT2 ：添加了原始的/ var / lib / lxc / stash / config文件：

 # Template used to create this container: /usr/share/lxc/templates/lxc-centos # Parameters passed to the template: # For additional config options, please look at lxc.container.conf(5) lxc.network.type = veth lxc.network.link = br0 lxc.network.hwaddr = fe:98:41:37:ca:3d lxc.network.flags = up lxc.rootfs = /var/lib/lxc/stash/rootfs # Include common configuration lxc.include = /usr/share/lxc/config/centos.common.conf lxc.arch = x86_64 lxc.utsname = stash lxc.autodev = 0 # When using LXC with apparmor, uncomment the next line to run unconfined: #lxc.aa_profile = unconfined # example simple networking setup, uncomment to enable #lxc.network.type = veth #lxc.network.flags = up #lxc.network.link = lxcbr0 #lxc.network.name = eth0 # Additional example for veth network type # static MAC address, #lxc.network.hwaddr = 00:16:3e:77:52:20 # persistent veth device name on host side # Note: This may potentially collide with other containers of same name! #lxc.network.veth.pair = v-stash-e0
